Description

Technical Field

[0001] The present invention relates to the field of sound, and particularly to a loudspeaker, an assembly method thereof, and a sound device. Background Art

[0002] Figures 1 to 3 Shown is a loudspeaker 100P of the prior art, which includes a frame 10P, a magnetic circuit system 20P, a diaphragm 30P, a surround 40P, and a voice coil 50P. The magnetic circuit system 20P is installed at the lower end 11P of the frame 10P. The outer and inner sides of the surround 40P extend to be connected to the upper end 12P of the frame 10P and the outer edge 31P of the diaphragm 30P respectively, so as to hold the diaphragm 30P at the upper end 12P of the frame 10P. The lower end 51P of the voice coil 50P and the magnetic circuit system 20P are magnetically connected to each other in an alternating manner, and the upper end 52P of the voice coil 50P is connected to the central position of the diaphragm 30P. The loudspeaker 100P has a central axis 101P. The central axis of the diaphragm 30P, the central axis of the surround 40P, and the central axis of the voice coil 50P all coincide with the central axis 101P of the loudspeaker 100P. That is, the diaphragm 30P is centrosymmetric with the central axis 101P of the loudspeaker 100P as the central symmetry axis, the surround 40P is centrosymmetric with the central axis 101P of the loudspeaker 100P as the central symmetry axis, and the voice coil 50P is centrosymmetric with the central axis 101P of the loudspeaker 100P as the central symmetry axis. When the loudspeaker responds to the input of an audio signal, the magnetic circuit system 20P and the voice coil 50P interact with each other to drive the diaphragm 30P to reciprocate along the central axis 101P of the loudspeaker 100P. In this way, the diaphragm 30P can agitate the air to generate sound waves, and the surround 40P is used to limit the stroke of the diaphragm 30P to ensure the movement direction of the diaphragm 30P.

[0003] Figure 4 and Figure 5An audio device of the prior art is shown, which includes a cabinet 200P and a speaker 100P mounted on the cabinet 200P. When designing the existing audio device, in order to ensure the aesthetics of the audio device, the speaker 100P is mounted on the center line of the front baffle 201P of the cabinet 200P, so that the distances from the central axis 101P of the speaker 100P to the two side edges of the front baffle 201P are exactly equal. This will cause diffraction at the edges of the cabinet 200P of the audio device, affecting the sound quality of the audio device. To reduce or even avoid the diffraction problem, the existing audio devices all adopt the method of designing the shape of the cabinet 200P. For example, the cabinet 200P is designed to be asymmetric to avoid the distances from the central axis 101P of the speaker 100P to the two side edges of the cabinet 200P being equal. This method not only requires the designer to have professional acoustic knowledge, but also causes the cabinet 200P to not be able to be designed into a regular shape. Specifically, Figure 6A shows the radiation state of the left reflected sound wave 1000P reflected from the left edge of the front baffle 201P of the cabinet 200P, Figure 6B shows the radiation state of the right reflected sound wave 2000P reflected from the right edge of the front baffle 201P of the cabinet 200P, attached Figure 6C shows the radiation state of the composite sound wave 3000P formed after the left reflected sound wave 1000P and the right reflected sound wave 2000P meet. At this time, the time when the wave crest of the left radiation sound wave 1000P appears is the same as the time when the wave crest of the right radiation sound wave 2000P appears, so that the composite sound wave 3000P will suddenly superimpose, seriously affecting the sound quality of the audio device.

[0070] According to the content disclosed in the claims and the specification of the present invention, the technical solution of the present invention is specifically as described below.

[0071] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0072] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as limiting the quantity.

[0073] Referring to the attached Figures 7A to 9 In the following description, a loudspeaker 100 according to a preferred embodiment of the present invention is disclosed and described, wherein the loudspeaker 100 includes a frame 10, a magnetic circuit system 20, a suspension 30, a diaphragm 40, and a voice coil 50.

[0074] The frame 10 has a frame low end 11 and a frame high end 12 corresponding to the frame low end 11.

[0075] The magnetic circuit system 20 has a magnetic gap 21 and a magnetic gap opening 22 communicating with the magnetic gap 21. The magnetic circuit system 20 is installed at the frame low end 11 of the frame 10, and the magnetic gap opening 22 of the magnetic circuit system 20 faces the frame high end 12 of the frame 10.

[0076] The diaphragm 40 has a diaphragm outer side 41. The suspension 30 has a suspension inner side 31 and a suspension outer side 32 corresponding to the suspension inner side 31. The suspension inner side 31 of the suspension 30 extends inward to be connected to the diaphragm outer side 41 of the diaphragm 40. Correspondingly, the suspension outer side 32 of the suspension 30 extends outward to be connected to the frame high end 12 of the frame 10, so as to hold the diaphragm 40 at the frame high end 12 of the frame 10 by the suspension 30.

[0077] The voice coil 50 has a voice coil low end 51 and a voice coil high end 52 corresponding to the voice coil low end 51. The voice coil low end 51 of the voice coil 50 extends through the magnetic gap opening 22 of the magnetic return system 20 to and is movably held in the magnetic gap 21 of the magnetic return system 20, and the voice coil low end 51 of the voice coil 50 and the magnetic return system 20 are magnetically connected to each other in an alternating manner. Correspondingly, the voice coil high end 52 of the voice coil 50 extends to and is connected to the diaphragm 40 to define a driven position 42 of the diaphragm 40. The driven position 42 of the diaphragm 40 is offset from the central axis 101 of the speaker 100, and the active axis 102 of the speaker 100 passes through the driven position 42 of the diaphragm 40. In other words, the active axis 102 of the speaker 100 is offset from the central axis 101.

[0078] When the speaker 100 responds to the input of an audio signal, the magnetic return system 20 and the voice coil low end 51 of the voice coil 50 magnetically communicate with each other, allowing the magnetic return system 20 to drive the diaphragm 40 along the active axis 102 of the speaker 100 to reciprocate at the driven position 42 of the diaphragm 40 through the voice coil 50, thereby agitating the air to radiate sound waves outward. The suspension 30 is used to limit the stroke of the diaphragm 40 and ensure that the diaphragm 40 reciprocates along the active axis 102 of the speaker 100.

[0079] Preferably, the active axis 102 of the speaker 100 passes through the center of gravity position of the diaphragm 40. In this way, when the voice coil 50 drives the diaphragm 40 to reciprocate along the active axis 102 of the speaker 100 at the driven position 42 of the diaphragm 40, the diaphragm 40 can be kept horizontal and avoid skew, thus ensuring the sound quality of the speaker 100.

[0080] Refer to the appendix Figures 7A to 9, in the loudspeaker 100 of the present invention, the diaphragm 40 has a paraxial position 43 and an off-axis position 44 corresponding to the paraxial position 43. The paraxial position 43 of the diaphragm 40 refers to the position of the edge of the outer side 41 of the diaphragm 40 closest to the active axis 102 of the loudspeaker 100. Correspondingly, the off-axis position 44 of the diaphragm 40 refers to the position of the edge of the outer side 41 of the diaphragm 40 farthest from the active axis 102 of the loudspeaker 100. In the loudspeaker 100 of the present invention, the thickness dimension of the diaphragm 40 gradually thins from the paraxial position 43 to the off-axis position 44, so that the center of gravity position of the diaphragm 40 is close to the paraxial position 43 and far from the off-axis position 44. In this way, the active axis 102 of the loudspeaker 100 can pass through the center of gravity position of the diaphragm 40. Thus, when the voice coil 50 drives the diaphragm 40 to reciprocate along the active axis 102 of the loudspeaker 100, the diaphragm 40 can remain horizontal and avoid tilting, so as to ensure the sound quality of the loudspeaker 100.

[0081] Further, referring to the attached Figures 7A to 9 , the frame 10 includes a lower-end frame 13 and a higher-end frame 14 mounted on the lower-end frame 13. The lower-end frame 13 forms the lower end 11 of the frame 10. The magnetic circuit system 20 is mounted on the lower-end frame 13 so that the magnetic circuit system 20 is held at the lower end 11 of the frame. Correspondingly, the higher-end frame 14 forms the upper end 12 of the frame 10. The outer side 32 of the suspension 30 is connected to the higher-end frame 14, so that the diaphragm 40 is held at the upper end 12 of the frame.

[0082] More specifically, referring to the attached Figure 7B and Figure 8 , the lower-end frame 13 further includes a magnetic-circuit mounting ring 131, a joining ring 132, and a plurality of spaced-apart connecting arms 133 extending between the magnetic-circuit mounting ring 131 and the joining ring 132. The magnetic-circuit mounting ring 131 of the lower-end frame 13 is mounted on the magnetic circuit system 20 in a manner surrounding the outer side of the magnetic circuit system 20, so that the magnetic circuit system 20 is mounted on the lower-end frame 13. The central axis of the magnetic-circuit mounting ring 131 and the central axis of the joining ring 132 are offset from each other and do not coincide. In this way, the central axis of the magnetic circuit system 20 mounted on the magnetic-circuit mounting ring 131 and the central axis of the joining ring 132 are offset from each other and do not coincide.

[0083] Accordingly, the high-end frame 14 includes a retaining ring 141 and at least two engaging arms 142 extending downward from the retaining ring 141, wherein the outer side 32 of the overhang of the overhang 30 is connected to the retaining ring 141 of the high-end frame 14 to allow the retaining ring 141 to surround the periphery of the drum paper 40. The engaging arms 142 of the high-end frame 14 are mounted on the engaging ring 132 of the low-end frame 13, and the central axis of the retaining ring 141 of the high-end frame 14 coincides with the central axis of the engaging ring 132 of the low-end frame 13, such that the central axis of the magnetic return system 20 and the central axis of the retaining ring 141 deviate from each other and do not coincide.

[0084] It should be noted that in the loudspeaker 100 of the present invention, the central axis of the retaining ring 141 of the high-end frame 14 and the central axis of the engaging ring 132 of the low-end frame 13 determine the central axis 101 of the loudspeaker 100, and the central axis 101 of the loudspeaker 100, the central axis of the retaining ring 141 of the high-end frame 14, and the central axis of the engaging ring 132 of the low-end frame 13 coincide with each other. Accordingly, the central axis of the magnetic return system 20 determines the moving axis 102 of the loudspeaker 100, and the moving axis 102 of the loudspeaker 100 and the central axis of the magnetic return system 20 coincide with each other. In the loudspeaker 100 of the present invention, the central axis of the magnetic return system 20 deviates from the central axis of the retaining ring 141 of the high-end frame 14 and the central axis of the engaging ring 132 of the low-end frame 13, so that the moving axis 102 of the loudspeaker 100 deviates from the central axis 101.

[0085] In the appendix Figures 7A to 9In this preferred example of the illustrated loudspeaker 100, the diaphragm 40 can be formed by injection molding, so that the thickness dimension of the diaphragm 40 gradually thins from the paraxial position 43 to the far-axis position 44. The forming method of the surround 30 is not limited in the loudspeaker 100 of the present invention. For example, in a specific example of the loudspeaker 100 of the present invention, the surround 30 is prefabricated, wherein the inner side 31 of the surround 30 of the surround 30 can be bonded to the outer side 41 of the diaphragm 40 by an adhesive substance such as glue. Correspondingly, the outer side 32 of the surround 30 of the surround 30 can be bonded to the retaining ring 141 of the high-end frame 14 by an adhesive substance such as glue. In another specific example of the loudspeaker 100 of the present invention, the surround 30 is integrally formed between the diaphragm 40 and the retaining ring 141 of the high-end frame 14, so that the inner side 31 of the surround 30 of the surround 30 is integrally connected to the outer side 41 of the diaphragm 40 during the forming process of the surround 30, and the outer side 32 of the surround 30 of the surround 30 is integrally connected to the retaining ring 141 of the high-end frame 14 during the forming process of the surround 30.

[0086] Continuing to refer to the appended Figures 7A to 9 , the loudspeaker 100 further includes a stabilizer 60, the stabilizer 60 having a stabilizer inner side 61 and a stabilizer outer side 62 corresponding to the stabilizer inner side 61, wherein the stabilizer inner side 61 of the stabilizer 60 extends to and is connected to the voice coil 50, and the stabilizer outer side 62 of the stabilizer 60 extends to and is connected to the frame 10. When the magnetic circuit system 20 drives the voice coil 50 to reciprocate along the moving axis 102 of the loudspeaker 100, the voice coil 50 can drive the stabilizer 60 to deform, so as to limit the reciprocating movement direction of the voice coil 50 by means of the stabilizer 60 and prevent the movement direction of the voice coil 50 from deviating from the moving axis 102 of the loudspeaker 100.

[0087] Furthermore, the low-end frame 13 includes a joint platform 134, wherein the joint platform 134 extends inward from the joint ring 132, and the stabilizer outer side 62 of the stabilizer 60 is connected to the joint platform 134 of the low-end frame 13.

[0088] It is worth mentioning that the shape of the stabilizer 60 is not limited in the loudspeaker 100 of the present invention. For example, in the appended Figures 7A to 9In this specific example of the illustrated loudspeaker 100, the axis stabilizer 60 can be implemented in a shape similar to that of the surround, that is, the cross-sectional shape of the axis stabilizer 60 can be "U"-shaped, or the cross-sectional shape of the axis stabilizer 60 can be "S"-shaped, or the cross-sectional shape of the axis stabilizer 60 can be wavy. In other specific examples of the loudspeaker 100 of the present invention, the axis stabilizer 60 can be a spider.

[0089] Continuing to refer to the appendix Figures 7A to 9 , the loudspeaker 100 further includes a dust cap 70, wherein the dust cap 70 is mounted on the upper end 52 of the voice coil of the voice coil 50 to close the upper end opening of the voice coil 50, thereby preventing dust from entering the interior of the voice coil 50. The shape of the dust cap 70 is not limited in the loudspeaker 100 of the present invention, and it can be a hemispherical structure or a flat plate structure.

[0090] It is worth mentioning that the shape of the diaphragm 40 is not limited in the loudspeaker 100 of the present invention. For example, in this specific example of the illustrated loudspeaker 100 in the appendix Figures 7A to 9 , the diaphragm 40 can be a horn-shaped structure, while in another specific example of the illustrated loudspeaker 100 in the appendix Figure 10 and Figure 11 , the diaphragm 40 can be a flat plate structure.

[0091] The appendix Figure 12 shows a modified example of the loudspeaker 100. Different from the loudspeaker 100 shown in the appendix Figures 7A to 9 , in this modified example of the loudspeaker 100 shown in the appendix Figure 12 , the thickness dimensions of the diaphragm 40 are consistent at each position, and the thickness dimension of the surround 30 gradually thins from the position of the surround 30 corresponding to the near-axis position 43 of the diaphragm 40 to the position of the surround 30 corresponding to the far-axis position 44 of the diaphragm 40. In this way, the center of gravity position of a vibration mechanism 103 formed by the surround 30 and the diaphragm 40 is close to the near-axis position 43 of the diaphragm 40 and far from the far-axis position 44. In this way, the active axis 102 of the loudspeaker 100 can pass through the center position of the vibration mechanism 103. Thus, when the voice coil 50 drives the diaphragm 40 to reciprocate along the active axis 102 of the loudspeaker 100, the diaphragm 40 can remain horizontal and avoid tilting to ensure the sound quality of the loudspeaker 100.

[0092] It is worth mentioning that in the appendix Figure 12In this specific example of the illustrated loudspeaker 100, the diaphragm 40 can be made by an injection molding process or by bending a flat structure and bonding the free ends.

[0093] Attached Figure 13 Shows another variant example of the loudspeaker 100. Different from the attached Figures 7A to 9 Shown loudspeaker 100, in this variant example of the illustrated loudspeaker 100 Figure 12 In this variant example of the illustrated loudspeaker 100, the thickness dimensions of the diaphragm 40 are consistent at various positions. Among them, the thickness dimension of the glue layer 80 of the inner side 31 of the suspension edge for bonding the suspension edge 30 and the diaphragm 40 to the outer side 41 of the diaphragm gradually thins from the near-axis position 43 to the far-axis position 44 of the diaphragm 40. In this way, the center of gravity position of the vibration mechanism 103 formed by the suspension edge 30, the diaphragm 40 and the glue layer 80 is close to the near-axis position 43 of the diaphragm 40 and far from the far-axis position 44. In this way, the active axis 102 of the loudspeaker 100 can pass through the center position of the vibration mechanism 103. Thus, when the voice coil 50 drives the diaphragm 40 to reciprocate along the active axis 102 of the loudspeaker 100, the diaphragm 40 can remain horizontal and avoid tilting, so as to ensure the sound quality of the loudspeaker 100.

[0094] It is worth mentioning that, in this specific example of the illustrated loudspeaker 100 Figure 13 The diaphragm 40 can be made by an injection molding process or by bending a flat structure and bonding the free ends. The suspension edge 30 needs to be prefabricated.

[0095] According to another aspect of the present invention, the present invention further provides an assembly method of the loudspeaker 100, wherein the assembly method includes the following steps:

[0096] (a) Install the magnetic circuit system 20 on the magnetic circuit mounting ring 131 of the low-end frame 13 in such a way that the central axis of the magnetic circuit system 20 deviates from the central axis of the engagement ring 132 of the low-end frame 13;

[0097] (b) Allow the inner side 31 and the outer side 32 of the suspension edge 30 to be respectively connected to the outer side 41 of the diaphragm 40 and the retaining ring 141 of the high-end frame 14; and

[0098] (c) Mount the high - end frame 14 on the low - end frame 13 in such a way that the central axis of the retaining ring 141 coincides with the central axis of the engaging ring 132, so that the voice coil 50 connected to the driven position 42 of the diaphragm 40 extends towards the magnetic circuit system 20 and is magnetically connected to the magnetic circuit system 20 in an alternating manner, and the driven position 42 of the diaphragm 40 is offset from the central axis 101 of the speaker 100 to assemble the speaker 100.

[0099] In a specific example of the speaker 100 of the present invention, the step (b) further includes the steps of:

[0100] Injection - mold the diaphragm 40 so that the thickness dimension of the diaphragm 40 gradually thins from the near - axis position 43 of the diaphragm 40 to the far - axis position 44; and

[0101] Integrally form the surround 30 between the diaphragm 40 and the retaining ring 141 of the high - end frame 14.

[0102] In another specific example of the speaker 100 of the present invention, the step (b) further includes the step of integrally forming the surround 30 between the diaphragm 40 and the retaining ring 141 of the high - end frame 14, wherein the thickness dimension of the surround 30 gradually thins from the position of the surround 30 corresponding to the near - axis position 43 of the diaphragm 40 to the position of the surround 30 corresponding to the far - axis position 44 of the diaphragm 40.

[0103] In another specific example of the speaker 100 of the present invention, the step (b) further includes the steps of:

[0104] Apply glue to the inner surround 31 of the surround 30 and / or the outer diaphragm 41 of the diaphragm 40 to bond the inner surround 31 of the surround 30 and the outer diaphragm 41 of the diaphragm 40, wherein the thickness dimension of the glue layer 80 held between the inner surround 31 of the surround 30 and the outer diaphragm 41 of the diaphragm 40 gradually thins from the near - axis position 43 of the diaphragm 40 to the far - axis position 44; and

[0105] Apply glue to the outer surround 32 of the surround 30 and / or the retaining ring 141 of the high - end frame 14 to bond the outer surround 32 of the surround 30 and the retaining ring 141 of the high - end frame 14.

[0106] Attach Figures 14 to 17CAn audio device according to a preferred embodiment of the present invention is shown, wherein the audio device includes the speaker 100 and a box 200, wherein the box 200 has a front baffle 201, and the speaker 200 is installed on the front baffle 201 of the box 200.

[0107] In the audio device of the present invention, the driven position 42 of the drum paper 40 of the speaker 100 is offset from the central axis of the speaker 100. Therefore, even if the speaker 100 is mounted in the middle of the front baffle 201 of the cabinet 200, the portions of the cabinet 200 located on either side of the active axis 102 of the speaker 100 will not be equidistant. This effectively reduces or even eliminates diffraction issues, thereby maintaining the sound quality of the audio device. Furthermore, the audio device reduces or even eliminates diffraction issues without requiring specialized design of the cabinet 200, allowing designers unfamiliar with or even lacking professional knowledge of acoustics to easily design an audio device with good sound quality.

[0108] Further, refer to the attached Figures 16 to 17C When the sound waves generated by the speaker 100 radiate toward both sides of the cabinet 200, there is a time difference between the sound waves reaching the left edge and the right edge of the front baffle 201 of the cabinet 200. In this way, when the left reflected sound wave 1000 reflected by the left edge of the front baffle 201 and the right reflected sound wave 2000 reflected by the right edge meet to form a composite sound wave 3000, the peaks and troughs of the left reflected sound wave 1000 and the peaks and troughs of the right reflected sound wave 2000 will be staggered to avoid excessive superposition of the left reflected sound wave 1000 and the right reflected sound wave 2000, thereby reducing or even avoiding diffraction problems.
